Lip augmentation, using lip implants or dermal fillers, increases lip volume by filling any creases related to the aging process along the lip border. The surgeon makes small incisions at the corners of the mouth to create a thin tunnel in which to insert the implant and thread it through the lip. The lip implant is trimmed to the proper length and the incisions are closed. Popular lip implants include GORE-TEX, SoftForm and AlloDerm. GORE-TEX has micropores through which the natural lip tissue grows. SoftForm lip implants have a tubular shape that lessens the chance of migration. AlloDerm is made from donated skin and has few allergic responses.
